Red4:
I feel your pain! Literally! I too in the not so distant past have impaled my right index finger with an xacto blade. However, I didn't cut the tip off. I decided to try and cut through the glue that was holding a figure to a temporary base. It went alot smoother than I thought it would and I ened up driving 1/2 of an xacto blade directly into the side of my finger at about Mach 3. There's still a bump where it healed funny.
If you would like, I could remove the bump and mail it to you as a replacement for the tip of your finger.
OK..now I've just grossed myself out.
I'll echo your warning to everyone as well
"BE SAFE"
